JAMES GRANGER, OF ZANESVIIJLE, OHIO.

IMPROVED PADDLE=WHEEL.

To all whom it may concern:

Be it known that I, JAMEs GRANGER, of Zanesville, in the county of Muskingum and State of Ohio, haveinvented new and useful Improvements in Paddle-Wheels; and I do hereby declarethat the following is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The present invention relates to that class paddle-wheels in which the paddles are hung or attached at each end to endless chains passing over two wheels at each end,to which the necessary rotary movement is imparted in any proper manner; and it consists in so arranging he said wheels and hanging the paddles on nd to the endless chains that a sweep in a ircular direction will be given to the paddles their passage through the water, whereby ey are caused to continually press upon and :gainstit-a result of the utmost importance 'o the success of chain-wheels, and which with v, heels of a similar class now in use or heret'A fore invented has never been satisfactorilyr a fomplished.

1n the accompanying plate of drawings, Figure l represents an end elevation of a chain paddle-wheel made according to my improvements applied to a suitable stand for it, and Fig. 2 a plan or top view.

Similar letters of reference indicate like parts.

A in the drawings represents a stand, on which, for convenience of illustration, my improved chain paddle-wheel is hung, turning by its shafts B and O, respectively, having similar wheels or pulleys D and E at each of their ends, in uprights or standards F F at suitable distances apart therefor, the paddlewheels being' embraced iu and between the said uprights. Around these pulleys D and E, at e.' 3;. end of their respective shafts B and O, asses an endless chain, G, to which at suitable oints the paddles H H are hung, as will be ,presently explained, the number of which isffl be more or less according to the length of'ahe chains, and the points of hanging the paddles are to-be equidistant from each other.

AThe paddles H H are each secured at or near each end to the outer portion of an arm or holder, I, which holders at their inner ends are pivoted to the center of bridge-pieces J, hung in and between two of the links of the chain G, hereinbefore referred to, at the proper points, the said bridge-pieces beingof sufficient length, that as the chains pass from one pulley, D, to the other, E, they will span the entire length of chain between the two bearing-points of the pulleys, and thus support the paddles and give to them a circular movement, and also support and strengthen the chains, while at the same time they can'freely pass around either one or the other of the said pulleys D and E, as is plainly shown in the drawings, the distance between the two pulleys D and E at each end of the paddle-wheel being made equal and of the least possible length practicable.

lhe pulleys D D are the larger in diameter of the two sets D and E, and to their shaft is attached the driving power used for operatin g the paddle-wheels, they being placed toward the stern of the vessel on which the paddlewheels are to be hung, consequently bringing the other or smaller pulley, E, toward the bow. The stern-wheels D D are to be made sufficiently large to allow the requisite length of chains to be used to hold the desired number of paddles, and they are also made with a series of cogs, a a, upon and around their peripheries, which cogs interlock and enga-ge with the links of the chains as they pass around the wheels.

From the arms I at each end of the paddles H to the arms of the paddle next behind in each case extends a connecting-arm, M, pivoted at each end, and extending from a point at or near the bridge-pieces J of each paddle to a point at or near the outer ends of each of the said paddle-arms I, as is plainly shown in the drawings.

From the above description of the manner in which the paddles are hung upon the endless chains and the chain-wheels or pulleys arranged it will be seen that the paddles in traveling around will be caused to enter the water in an upright position, which is the most favorable position, and to move through the water with a circular sweep or direction.

The arms M, in lieu of being hung to the paddle-arms I or the paddles H, as described,

in which oase they operate to pull the paddles through the Water, firmly bracing and causing` them to run steady, may be hung to one paddle or its arm at or near its outer end, and to the neXt paddle-arm behind it, at or near its hinging-point, to the endless cha-in, when they will operate to push the paddles through the Water; but I do not deem it so desirable or practicable as that explained and shown.

The paddles H H may be hung' upon their respective arms I I by clasps b b, if so de sired, thus enabling,` them to be drawn out from or moved in and toward the endless chains, as is obvious.

I claim as new and desire to secure by Letters Patent- The combination of the paddles H, arms II, connecting-holders M, bridge-pieces J, endless chain G, and pulleys D E, constructed and arranged iu 'the manner and for the purpose herein specified.
